SHAFT-HOLDER.

Specification of Letters Patent.

Application filed August 17, 1907.

Patented June 30, 1908.

Serial No. 388,977.

To all whom it may concern:

Be it known that I, JAMES H. JENSEN, a

g at Brigham city, in the county of Boxe lder and State of Utah, have invented new and useful Improvements in Shaft-Holders, of which the following is a specification.

This invention relates to shaft hangers; and it has for its objects to provide a device of simple and improved construction whereby a line shaft may be supported for rotation, and which shall admit of lateral as well as vertical adjustment of the boxing which constitutes the shaft therein after the hanger has been secured in position, thus enabling inaccuracies to be corrected and the shaft to be su ported without being exposed unnecessari y to friction; further objects being to simplify I and improve the construction and operation of this class of devices.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement of p arts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawing has been illustrated a simple and preferred form of the invention; it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited,

ut that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

In the drawing Figure 1 is a side view of a shaft hanger constructed in accordance with the invention. Fig. 2 is a front view of the same. Fig. 3 is a transverse sectional view enlarged taken through the bearing box of the,hanger. Fig. 4 is a vertical sectional view taken through the supporting device.

Corresponding parts in the several figures are denoted by like characters of reference.

The improved hanger includes a bifurcated bracket member or yoke 1 adapted to be bolted or otherwise secured upon the under side of a ceiling or sup orting member such as a beam 2. The brac et 1 is provided with a vertical screw threaded aperture 2 for the passage of a bolt 3 upon which, adjacent to the head 4 at the lower end thereof, there is loosely supported a sleeve 5 having a laterally extending externally threaded arm 6. The sleeve 5 is secured upon the bolt 4 by means of a clamping nut 7; and a lock nut 8 fitted upon the bolt adjacent to the lower end of the bracket 1, serves to secure said bolt in any position to which it may be adjusted.

The externally threaded arm 6 that extends laterally from the sleeve 5 is provided with clamping nuts 99 engaging the ends of a sleeve consisting of a type section 10 which is thereby adjustably mounted upon the arm 6, as will be best seen by reference to Fig. 3 of the drawings. The bearing box 11 is provided on its under side with a collar 12 exteriorly engaging the sleeve 10 upon which the bearing box will thus be mounted in such a manner as to be capable of a rocking or oscillatory motion which will enable the said bearing box to seek its ro er position in true axial alinement wit the shaft supported therein, thus enabling such shaft to revolve freely within the bearing box.

It will be readily seen that by loosening the lock nut 8 and the clamping nut 7, the bolt supporting the sleeve 5 which in turn supports the bearing box may be moved up or down, thus effectin the desired vertical adjustment of the shaft bearing; lateral adjustment of said bearing being effected by adjusting the supporting sleeve 10 upon the arm 6.

By tightening the nuts, the several parts may be readily secured in adjusted osition, as will be readily understood. This improved device, as will be seen, is extremely simple; and it permits a delicacy of adjustment which is highly efficient in supporting the shaft without vibration, and in reducing friction to a minimum.

Having thus described the invention, what I claim as new, is

The herein described shaft-hanger comprising a detachable supporting bracket having a screw threaded a erture, a bolt engaging said aperture, said olt having a head at the lower end thereof, a sleeve loosely engaging the bolt and seated upon the head, a clamping nut enga ing the upper face of the sleeve, a lock nut i itted upon the bolt adj acent to the lower end of the bracket, said sleeve having a laterally extending externally threaded arm, a bearing sleeve mounted upon the laterally extending arm, a collar In testimony whereof I affix my signature mounted upon the blearinfi sleeve, a bearing in presence of two Wit/1165868.

box mounted u on t e co ar, nuts u on the arm and contac ing with the end face of the JAMES JENSEN sleeve and collar for securing the latter upon Witnesses:
